Chapter 3: Calibration 23

3 Calibration

• press the ALIGN TO COG soft key: the HEADING value will then be

aligned to the COG (course over ground) heading received from

the GPS and you will see the following pop-up message

• expect some difference between COG and the heading when the

boat turns

Note: If you press ALIGN TO COG when the SOG is less than 3 knots you

will see the warning message: SOG TOO LOW. CANNOT ALIGN TO COG.

Increase the boat’s speed then press ALIGN TO COG again.

3. Because many factors (such as tides and leeway affecting the boat)

can make the actual heading differ from COG, you may then need to

fine-tune the heading alignment (see below).

Fine-tune the alignment

1. Use the ADJUST HEADING soft keys to adjust the displayed heading so

it matches the boat’s steering compass or a known transit bearing.

2. Save the aligned heading by pressing the ENTER or CLEAR key to

return to the COMPASS SETUP menu.

Note: If you do not want to save the new aligned heading, press CANCEL

ALIGNMENT to return to the COMPASS SETUP menu and restore the

previous heading value.

3. Then press ENTER or CLEAR key twice to return to normal operation.
